i hope this helps (or even relates to whats being asked) 
but press F9 to change angle 
then when you are at the 3rd available angle 
dragging with the right mouse button will zoom out or in, giving u custom 3rd person view 
 
and holding CTRL (or clicking with right mouse) in first person allows u to strafe left or right with directional keys
